Kohelet 4:9-11

Orthodox Jewish Bible

⁹ Two are better than one because they have a sachar tov for their amal.

¹⁰ For if they fall, the echad will lift up his partner, but woe to him that is alone when he falleth; for he hath not another to help him up.

¹¹ Also, if two lie down, then they have chom (heat), but how can one be warm alone?
